Geological Summary

Table Top and Wide Bay cinder cones, at the NE tip of the triangular NW extension of Unalaska Island across the bay from the town of Dutch Harbor, blanket or fill late-Pleistocene topography. Both 792-m-high Table Top and the 640-m-high Wide Bay cones were considered to be Holocene in age, with the Wide Bay cone being among the youngest in a SW-NE-trending volcanic belt that passes through Makushin volcano (Miller et al., 1998), however, a later 40Ar/39Ar age of 68+/-14 ka was obtained from Table Top (AVO, 2005-). Table Top Mountain cone has an associated lava apron and was considered to represent a magmatic system separate from that of Makushin volcano and Wide Bay cone (Nye, pers. comm. 2008).

This volcano is located within the Aleutian Islands, a UNESCO Biosphere Reserve property.

Flat-topped Table Top cinder cone (upper right) lies at the NE tip of the triangular NW extension of Unalaska Island. Table Top and its associated lava apron (center) blanket or fill late-Pleistocene topography. Both Table Top and the Wide Bay cone to the east were considered to be Holocene in age, with the Wide Bay cone (just out of view to the right) being among the youngest in a SW-NE-trending volcanic belt that passes through Makushin volcano to the SW.

The Sentinel Hub Playground provides a quick look at any Sentinel-2 image in any combination of the bands and enhanced with image effects; Landsat 8, DEM and MODIS are also available. Sentinel Hub is an engine for processing of petabytes of satellite data. It is opening the doors for machine learning and helping hundreds of application developers worldwide. It makes Sentinel, Landsat, and other Earth observation imagery easily accessible for browsing, visualization and analysis. Sentinel Hub is operated by Sinergise

Incorporated Research Institutions for Seismology (IRIS) Data Services map showing the location of seismic stations from all available networks (permanent or temporary) within a radius of 0.18° (about 20 km at mid-latitudes) from the given location of Table Top. Users can customize a variety of filters and options in the left panel. Note that if there are no stations are known the map will default to show the entire world with a "No data matched request" error notice.

WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.

EarthChem develops and maintains databases, software, and services that support the preservation, discovery, access and analysis of geochemical data, and facilitate their integration with the broad array of other available earth science parameters. EarthChem is operated by a joint team of disciplinary scientists, data scientists, data managers and information technology developers who are part of the NSF-funded data facility Integrated Earth Data Applications (IEDA). IEDA is a collaborative effort of EarthChem and the Marine Geoscience Data System (MGDS).
